h2. Kerberos

h3. How to set up kerberos

<pre>

$ mv /etc/krb5.conf /etc/krb5.conf.bak

$ cd /etc

$ wget http://security.fnal.gov/krb5.conf

$ echo "host cdcvs.fnal.gov

   ForwardX11 = no

   GSSAPIAuthentication yes

   GSSAPIDelegateCredentials yes" >> ~/.ssh/config

$ kinit -f your-fnal-username

$ klist

h2. Creating a sub-project repository

* Creating a Repository in a Sub-Project: see https://cdcvs.fnal.gov/redmine/projects/fermi-redmine/wiki/CreatingRepositories

* setting up a repository on your local machine (which will then be pushed/pulled to/from the FRedmine (FNAL Redmine) repository you created:

h3. Example-ish

* If you have a project "fred" and a "main" repository with no identifier

you get put in

** /cvs/projects/fred

* if you have a project fred and a repository identifier of "joe" you get

** /cvs/projects/fred-joe

* So you can do give them all identifiers, or have one (main) one without;

or you can give the Main one an identifier...

* If there is no "Main" repository, the Repository tab doesn't show up,

apparently.
